Quantum immortality

If you are not comfortable knowing that you are immortal in pi, maybe you can be comfortable with the idea of Quantum Immortality. To understand this concept, first we must understand the many-worlds interpretation of quantum mechanics. Hugh Everett Ill s doctoral thesis, Relative State Formulation of Quantum Mechanics (reprinted in Reviews of Modern Physics), outlines a controversial theory in which the universe at every instant branches into countless parallel worlds. However, human consciousness works in such a way that it is only aware of one universe at a time. 

Those who believe in Quantum Immortality say that the many-worlds interpretation of quantum mechanics implies that a conscious being can live forever. The cancer you have will not kill you. Your fatal car accident ten years from now will never take place. The theory also means that suicide bombers continue to exist, even after their backpacks explode. The strange logic for quantum immortality becomes clear in the following paragraph. 

Quantum Immortality, from Wikipedia, the Free Encyclopedia, http //en.wikipedia.org/wiki/Quantum immortality... 

On 6 October 2000 Per-Olov Lowdin left us. for many of us, he had seemed immortal, a constant friend and colleague in the now vast field of Quantum Chemistry to which he had devoted so much of his creative energy. 

During my student days (pre-university, university, PhD), we learned quantum mechanics from the books authored by L. D. Landau and E. M. Lifshitz, A. S. Davydov, D. Bohm, Feynman s course of Lectures on Physics, and from P. A. M. Dirac s Principles . We were exeited with the theories of hidden variables, EPR paradox, decoherence, entanglement, and concerned for a life of immortal Schrodinger s cat - they were in the air at that time Did I understand it Yes - because, due to a conventional wisdom, I used it more than 24 hours a day and every day. I however doubt - doubt together with Feynman who once remarked that Nobody understands it - that I ve actually understood it. I touched and used it throughout the molecular world, which is nowadays inhabited by 21 million molecules, and which I studied as a quantum chemist - in fact, by education, I am a theoretical physicist.
